摘要： A method for the encapsulation and triggered-release of water-soluble or water-dispersible materials. The method comprises a) providing an amount of electrolyte having a charge, b) providing an amount of counterion having a valence of at least 2, c) combining the polyelectrolyte and the counterion in a solution such that the polyelectrolyte self-assembles to form aggregates, d) adding a compound to be encapsulated, and e) adding nanoparticles to the solution such that nanoparticles arrange themselves around the aggregates. Release of the encapsulated species is triggered by disassembly or deformation of the microcapsules though disruption of the charge interactions. This method is specifically useful for the controlled viscosity reduction of the fracturing fluids commonly utilized in the oil field.

摘要： Methods of nanoencapsulation are described herein. Embodiments of the method utilize the coacervation of a cationic polyelectrolyte with an anionic polyelectrolyte to form a novel capsular matrix. In particular, the novel methods may be used to encapsulate a suspension of a hydrophobic material such as a carotenoid. The disclosed methods do not require lengthy pH adjustments nor do they require the use of any toxic crosslinking agents. In one embodiment, a method of encapsulation comprises dispersing a hydrophobic compound in an organic solvent to form a solution. The method also comprises admixing an anionic polyelectrolyte and a cationic polyelectrolyte with the suspension to form a mixture. In addition, the method comprises quiescently cooling the mixture so as to cause self-crosslinking of a capsular matrix encapsulating the hydrophobic particles.

摘要： New methods for the synthesis of nanocrystals/quantum dots are disclosed. The methods comprise use of reasonably-priced and commercially available heat transfer fluids (such as Dowtherm(R) A) as solvents to synthesize CdSe nanocrystals. Separation of nucleation and growth is achieved by quenching the reaction solution with relatively cold (room temperature) solvent to lower the solution temperature. Quenching may be followed by raising the solution temperature, to allow controlled growth to take place.

The coated porous silicon can be used to make anodes and batteries. It is capable of alloying with large amounts of lithium ions, has a capacity of at least 1000 mAh/g and retains this ability through at least 60 charge/discharge cycles. A particular pSi formulation provides very high capacity (3000 mAh/g) for at least 60 cycles, which is 80% of theoretical value of silicon. The Coulombic efficiency after the third cycle is between 95-99%. The very best capacity exceeds 3400 mAh/g and the very best cycle life exceeds 240 cycles, and the capacity and cycle life can be varied as needed for the application.
